Keeping mixtures homogeneous

The WBN Batch-Type Ribbon Blender, with its slowly turning single shaft double counter-pitch ribbon screw, is the ideal machine to obtain high quality mixtures with fragile materials, at the same time conserving the physical properties of the product.

Batch-type WBN Ribbon Blenders consist of a horizontal, single shaft double counter-pitch ribbon screw housed in a tubular mixing drum, a central inlet or a rectangular shape inlet port over the entire length of the mixing drum, an outlet with central discharge outlet, a venting spout, two drum closing end plates complete with integrated air or gas-purged shaft seals, and a drive unit complete with power transmission.

Function :

• The outer helix moves the material from both ends of the vessel towards the centre, while the inner helix transfers the material towards both ends, performing a sort of convective mixing.
• The product is gently processed in a relatively short mixing time. Typically Batch-type WBN Ribbon Blenders are used for mixing dry PVC, dry powders or granules in general, as well as liquids and low-viscosity pastes.

Features :

• Capacity: 10 ~ 20,000 litres per batch
• Mixing time: 5 ~ 15 min
• End bearing assemblies with various types of air or nitrogen-purged shaft seals or grease sealing
• Heavy-duty mixing chamber manufactured from carbon steel or 304L / 316L stainless steel
• Stainless steel surface finish: grit silking, mirror polishing, glass bead blasting
• Large hopper inlet or multiple round inlet spouts

Benefits :

• Low maintenance
• Durable machine
• Power rating adapted to application
• Mixing know-how and test facilities
